"First of all, he had a great attitude doing work on a Sunday of the Labor Day holiday. Then he performed the task of replacing a toilet and two new valve stems, in a really efficient and professional way. Just cannot say enough about his skill and friendliness, and would recommend him with my highest regards!"

"In response to my 'phone call a man came to my house in less than an hour. After we agreed on the work to be done, he got to work immediately, replaced one toilet and repaired another in a few hours. It couldn't have been easier or more efficient."

"This guy is AWESOME. We got Jay in for a fairly simple plumbing job in the new bathroom, then we decided we wanted to get some new toilets, Jay said yes of course and it was done I also asked for new gas line no problem he said fixed. Then we asked him to fit three new vanities which she did efficiently and finally we asked the impossible about the new shower extending it out and he found a way. What can I say he did everything asked at a price that was very good he was an awful lot cheaper than the big boys because he doesn't have the overheads but I guarantee this guy gives you everything you ask for with a smile thank you Jay we will be using you again"

"I got a call from Kyle around 4:55 pm. He said he was able to come out around 7 pm, keep in mind, Hyper Flow closes at 5 pm. Kyle came out of his way after hours, ran a camera through my sewer line, snaked out the line, and then showed me on the camera the second time that the line was clearish. My main sewage line has been building up for a few years. Kyle gave me 3 different estimates for futures maintenance. I have already made an appointment for Kyle to come back out and do some more work. He is very up front, honest, and caring. He isn't just trying to get paid, Kyle is aware that life happens and works with customers to do what works best financially for the customer at the time of the job. I would recommend Kyle and Hyper Flow to anyone who is looking for a plumber with years of experience and has the best intrest for his customers."

"The toilets in one of our condominium rental units were backing up. We assumed that the line needed to be snaked. We calledAfford-A-Rooter and AJ came out to help us. After noting everything else was draining fine he realized it was the toilets themselves. Apparently, toilets build up a calcium deposit that can actually block flushing.. He told me what the problem was, and told me the best solution would be new toilets. It would have been as expensive to auger the crank toilets. He told me how much it would be if he were to do it, and, since I have replaced toilets in the past I told him I could do it myself. He agreed that would be the quickest and cheapest solution. He did not charge me anything for the service call. I appreciated his honesty and we will definitely use this company again."

Toilets FAQs, answered by experts

If you notice water leaking down the side of the bowl or tank and you don’t notice any cracks in the porcelain, the odds are that it’s condensation. If you notice water around the base of the toilet, this points to a leak. Check for loose bolts. A sewage odor may also indicate a broken toilet flange.

First, check that you have cut off the water supply to your toilet. This is a project that can only be done safely if running water cannot reach your toilet fixture. If you're seeing water trickle out after you've confirmed that the water supply is shut off, you can probably rest assured that what you're seeing isn't a problem. It's common for leftover water to spill out when you're removing your toilet's fill valve. If something goes wrong while you're working on your toilet, you'll need to look at your home's policy to see if your homeowner insurance covers water damage.

If you decide to replace the toilet flapper yourself, the only cost will be buying the new flapper for around $5 to $17. You can also hire a plumber or handyperson to take on the job instead, in which case you’ll pay an hourly rate for labor plus the cost of parts. Handypersons charge $50 to $150 per hour, while plumbers cost $45 to $200 per hour. This repair might take less than an hour for your pro, but note that many providers have a minimum rate for a house call. 

Silicone-based caulk is known for its waterproofing qualities, so it’s the best option for any bathroom area. While it’s often more expensive, it will provide a better, longer-lasting seal than acrylic or latex caulk. Use it along the base of the toilet to prevent leaks and keep the area clean and protected.

You definitely can over-tighten toilet tank bolts. Unlike some other materials, porcelain can’t bend or flex, so when you over-tighten a screw into it, it could break against the added pressure. Only tighten them as much as needed to keep them in place and firm; any more and you could risk breaking the porcelain.
